Any errors in console (chrome dev tools) or in the logs (kestrel or appdata) ?

We see these script errors

Doesn't tell me much. Try looking into the log files too.

Have you tried:

1. All properties view in a different browser?
2. Inspected content types in Admin to identify any anomalies? i.e. properties that shouldn't be there.

it probably has more information in Network tab (check for failed requests) than the Console tab 

We were able to resolve the issue , a reference to a JS file was missing
